基于MSC.Patran的飞机壁板结构强度校核系统

Strength Evaluation System for Aircraft Panel Structures Based on MSC.Patran

在得到飞机壁板结构的有限元分析结果之后,需要利用工程方法对此计算结果进行评估,最终得到壁板结构的强度评估结果。以有限元软件MSC.Patran为平台,利用其二次开发语言PCL(PATRAN Command Language),通过自动加载编译函数文件、用户自定义菜单和图形界面和读取结果等技术,开发了飞机壁板结构强度校核系统。使用此系统对某些典型的壁板结构案例进行了分析,结果表明该程序不仅能够满足较大范围内的各种飞机壁板结构的强度校核要求,而且还可以大大提高飞机设计者的工作效率。

After getting the result from FEA in the aircraft panel structure model,one should add the engineering calculate method into this result to get the final strength evaluation for this panel structures.To implement the strength evaluation system for aircraft panel structures by modularization method,a program based on commercial software MSC.Patran is developed by using PCL language provided by MSC.Patran and journal file.The program is accomplished with start-up file,user self-defined menu and graphical interface,automatically running the analysis and reading results methods.Several typical cases are analyzed by the program and the results showed that the program can not only meet the variety requirement of aircraft panel structure evaluation,but also improve the efficiencies.
